Examples
O exemplo de código a seguir mostra um método substituído PartCommunicationMain que cria uma estrutura de dados CellReadyEventArgs para conter o valor da propriedade Cell , define o valor da propriedade e dispara o evento CellReady . Este exemplo de código é parte de um exemplo maior fornecido para a interface ICellProvider .
' Step #10: Override the PartCommunicationMain() method.
' The PartCommunicationMain method is called by the Web Part
' infrastructure on the client during
' the ASP.NET PreRender event to allow the part to pass its
' primary data to the other connected parts.
' It is important to always fire the CellReady event. Some parts
' may not behave properly if they are left waiting for this
' information.
Public Overrides Sub PartCommunicationMain()
' Check if connected.
If _connected Then
' If there is a listener, fire the CellReady event.
If Not (CellReady Is Nothing) Then
' Create the CellReadyEventArgs data structure for the
' CellProviderInit event.
Dim cellReadyArgs As New CellReadyEventArgs()
' If the user clicked the button, then send the value.
If _cellClicked Then
' Set the cell to the value of the TextBox text.
' This is the value that will be sent to the Consumer
cellReadyArgs.Cell = _cellInput.Text
Else
' The user didn't actually click the button
' so just send an empty string to the consumer.
cellReadyArgs.Cell = ""
End If
' Fire the CellReady event.
' The Consumer will receive the cell value in its
' CellReady event handler
RaiseEvent CellReady(Me, cellReadyArgs)
End If
End If
